Multiple Ports on One Housing

TXRota · 03-16-2012, 09:20 PM

Does anyone have any experience or knowledge with porting the same housing multiple times?

What do you Mean? If you port it bigger than the new port your screwed, I have ported housing that were previously ported. Of course the new port was bigger than the old one.

Na combining ports on one housing...like bp & pp on one housing

I'm pretty sure that a few have done bridge ported irons with semi PP housings. Try contacting Judge Ito, he was a member here. This would be combo porting not porting multiple times. Now on the other hand like RXspeed said you can enlarge a previous port job to a degree.

Ito is still a member here. His ego has caused HIMSELF to not want to post here anymore.

It is multiple porting, porting a housing more than once on one housing

RotorDad · 03-17-2012, 06:45 PM

Going from a mild street to a large street to a bridge is multiple times, all these ports are in the irons / side ports. The peripheral port is in the housing so by having the semi peripheral I would say combo not multiple unless you are just talking about the irons.

BTW google can be your friend or the search feature on the forums.

Same reason anyone does anything to a rota...more power

If you're having to consider a PP with BP then you need to invest in an FI setup. I've heard of 2 rotor FI setups making 800+ HP in drag cars, and I'm sure they're not doing anything like what you're suggesting.

The fuel efficiency and life expectancy of that motor would make it completely useless.

What are the plans for the vehicle, what kind of goals were you looking to achieve. I could be wrong, but I think Ted's question of why is looking for info. That way the members here can better suggest options for you & point you in the right direction.

O in that case, experience & experimentation...I've seen a shop in Japan do what I was asking & I wanted to see if anyone knew somethin similar
